Having read the source material and heard the man speak on his positions relative to it, this is not the intent of that statement.
Germaine to this conversation are two notions of truth as Tyson would state it: Objective and Personal.
Objective truths are empirical, testable and based on quantifiable results.
Personal truths are beliefs that individuals hold true for whatever non empirical reasons that are therefor not transferable to other individuals.
Believers can absolutely base decisions on Objective truths, because most of them do so all the time throughout daily life. Non-believers can also base decisions on Personal truths.
The point of Tyson's statement is to illustrate that it is a bad idea to allow policy decisions to be dictated by anything other than Objective truths.
